Benefits of technology
Enables cost-effective and secure delivery of data communication services by efficiently integrating general-purpose and hardware-trusted NFVI systems, allowing VNFs to be shared and executed securely across different hardware trust boundaries, enhancing services like video conferencing and multimedia messaging.
Problems solved by technology
Unfortunately, the NFVIs do not effectively integrate general-purpose NFVI systems with hardware-trusted NFVI systems.
Moreover, the general-purpose NFVI systems and the hardware-trusted NFVI systems do not efficiently share VNFs.
Unfortunately, NFV MANO systems do not efficiently share VNFs across the hardware-trust boundaries in the NFVIs.

Embodiment Construction
[0011]FIG. 1 illustrates Network Function Virtualization (NFV) system 100 to support a Network Service (NS) using Virtual Network Function (VNF) 102. The NS might be video conferencing, multimedia messaging, Internet access, or some other data communication service. NFV system 100 comprises NFV Infrastructure (NFVI) 101, network operations system 110, and NFV MANO data communication system 120. NFV MANO data communication system 120 includes NS control system 121 that comprises NFV Orchestration (NFVO) software and associated hardware. NFVI control system 122 that comprises VNF Manager (VNFM) and Virtualized Infrastructure Manager (VIM) software and associated hardware. Network operations system 110 and NFV MANO system 120 both comprise computer systems and software that may be discrete, shared, or hosted by another NFVI. For the typical NS, VNF 102 is chained to other VNFs and possibly to Physical Network Function (PNFs) by Virtual Links (VLs) based on VNF Forwarding Graphs (VNFFGs...

A wireless User Equipment (UE) comprises a Network Function Virtualization Infrastructure (NFVI) that has hardware-trusted circuitry to support a hardware-trusted wireless communication service. A Network Function Virtualization Management and Orchestration (NFV MANO) orchestrator executes in the hardware-trusted circuitry and exchanges hardware trust data with a wireless communication network to maintain hardware-trust. The NFV MANO orchestrator also exchanges network operations data for the hardware-trusted wireless communication service with the wireless network over an Os-Nfvo link. Responsive to the exchange of the network operations data, the NFV MANO orchestrator exchanges network service data with the hardware-trusted circuitry in the NFVI over an Nf-Vi link to execute an NFV Virtual Network Function (VNF) to support the hardware-trusted wireless communication service. Responsive to the exchange of the network service data, the hardware-trusted circuitry in the NFVI executes the NFV VNF to support the hardware-trusted wireless communication service.
Description
RELATED CASES[0001]This patent application is a continuation of U.S. patent application Ser. No. 14 / 753,536 that was filed on Jun. 29, 2015 and is entitled “NETWORK FUNCTION VIRTUALIZATION (NFV) HARDWARE TRUST IN DATA COMMUNICATION SYSTEMS.” U.S. patent application Ser. No. 14 / 753,536 is hereby incorporated by reference into this patent application.TECHNICAL BACKGROUND[0002]Data communication networks operate computer systems to provide various data services. The data services include internet access, media conferencing, file access, messaging, content delivery, and the like. The computer systems execute networking software to forward data packets for the data services. These computer systems increasingly use Network Function Virtualization (NFV) data processing infrastructures to execute the networking software.[0003]The NFV Infrastructures (NFVIs) distribute the execution of the networking software across various processing cores, time cycles, memories, and I / O ports. The networki...
